Yes i did, usually i just let certain topics pass by me and never comment here.

RF-cavities though are the very core to my line of research, so my acceptance for bs is very low in this regard.

If one wants to convince me of a thrust effect: build a prototype where the power source (a battery for example) and the RF-source are strapped onto the cavity, put the whole setup in a vacuum of your choice (i heard NASA has very nice and !large! facilities) and show me a sustained increase in impulse (just let it rotate for a while)

Yes, and the is the point.

NASA would have had the means to eliminate most of those sources of errors. I wouldn't call these measurement errors though -> the measurement is fine - your setup is the source of error.

But they decided not to follow such a line of research.

And yes, they are right "We believe that this is a good education project to track down measurement errors".

The measurement error being the "thrust" that is due to your experimental setup.

But let them waste some more money, time and reputation and build this in space so they can find out it does not actually work.

I am blaming them for not being up to date on the state of the art and not following up on earlier research, especially on what has been hinted at in: https://tu-dresden.de/ing/maschinenwesen/ilr/rfs/ressourcen/...

First you have to completely decouple the cavity from it's surrounding environment - especially the RF-field has to be generated by an apparatus fixed to the cavities frame of reference. Also the power has to come from a source connected to this frame of reference.

For me this is Physics 101.

As otherwise your system is not even closed. You are just neglecting that you are pumping LOTS of energy into an open system that you are measuring while assuming it to be closed -> thus leading to wrong conclusions (measuring a change in impulse in one part of the system)

For me this in line with uBeam and the like.

Whacko-science wherever one looks.

Thanks for posting a link to the paper!

There was a very elaborate experiment in Germany regarding this.

They concluded that the force is excerted by coupling the RF-energy from the outside.

If the system is fully self-contained (driven by a battery physically connected to the cavity) there is no thrust to be measured.

It's very sad to see NASA being involved in such shitty research.
